PVI, so the power used would be 240*5= 1200 Watts.
No, according to many pictures taken in space, the moon is white. However, on rare occasions, the moon appears blue.
Hope this helps! ☺♥
Density = (mass) / (volume), no matter how large or small the sample is.
We can't calculate the density, because you left out the number for the volume.
Also, you didn't tell us the unit for the mass of 180.
a). If the mass is 180 grams, then the density is
(180 gm) / (volume) .
b). No matter how many pieces you crush it into, and
no matter how large or small a piece is, its density is
the same. (I just wish we knew what the density really is.)
c). A piece may have 80 grams of mass. It doesn't "weigh" 80 grams.
Since the density of the whole rock is (180 gm) / (volume),
the density of any piece of it is (180 gm) / (volume).
Multiply each side by (volume): (Density) x (volume) = 180 gm
Divide each side by (density): Volume = (180 gm) / (density)
We can't calculate the volume of an 80-gm piece, because
we don't know the density. (That's because you left the volume
out of the question.)
Answer:
Energy, 
Explanation:
It is given that,
The MRI (Magnetic Resonance Imaging) body scanners used in hospitals operate at a frequency of 400 MHz,
We need to find the energy for a photon having this frequency. The energy of a photon is given by :
So, the energy of the photon is 
. Hence, this is the required solution.
